Answer:
The correct answer is given below:
Explanation:
1. A cleavage furrow or cell plate forms, separating the nuclei - Cytokinesis. During cell division, after division of nucleus, cytoplasm divides by furrow in an animal cells and by cell plate formation in the plant cells.
2. Chromosomes line up at the equator and chromatids are attached to spindle fibres—Metaphase. During metaphase all the chromosomes get arranged on the equatorial plane or the central plane
3. Nuclear membrane and nucleolus reappear- Telophase. The nuclear membrane starts to form around each of the daughter chromosomes and nucleolus also reappears in the daughter nuclei.
4. Genetic material replicates and is joined at the centromere- S-phase of the interphase. Duplication or copying of the DNA occurs in this phase
5. Centromeres divide and single-stranded chromosomes move to the poles- Anaphase. During anaphase, the sister chromatids of each chromosome gets separated and move to the opposite poles.
Instincts are the biologically determined, innate patterns of behavior.
Instincts are the intuitive feeling of a person towards a certain stimuli. These are inborn impulses. There are 6 basic human instincts. These are seeking, anger, fear, panic-grief, care, pleasure and play. Amongst all, seeking is considered to be the most powerful instinct.
Innate behavior is the habit that is present inside an organism by birth, may be genetically. No prior learning or experience is required for it. Examples of the same are: reflexes, taxis and kinesis, fixed action patterns and circadian rhythms. When a baby suckles after birth, it is an innate behavior.

Answer:
A) Divergent evolution because all of the species have similar structures during the first stage of development.
Explanation:
Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template.
